Chemical Structure
Description
The molecular framework of 1,1,1-Trifluoro-4-(methylthio)butan-2-ol (C5H9F3OS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
1,1,1-Trifluoro-4-(methylthio)butan-2-ol (CAS 1249021-52-0) is a high-purity analytical reference standard with the molecular formula C5H9F3OS and a molecular weight of 174.18 g/mol.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 1,1,1-Trifluoro-4-(methylthio)butan-2-ol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
